Robust Optimization, Empirical Likelihood, and Regularization
摘要:
We discuss stochastic optimization problems, in which the underlying probability distribution is unknown and needs to be estimated from observed data. Such optimization problems arise in many different settings, including online applications, finance, etc. We make clear the connection between a certain class of robust optimization procedures and generalized empirical likelihood. From this connection, we show how one can construct confidence intervals for optimal values and solutions that achieve exact coverage asymptotically. A key finding is that the distributionally robust formulation essentially regularizes the problem via the sample variance. This work is joint with John Duchi and Hongseok Namkoong.
